REIRFbRCED-CONCRETE PARTITION.

Specification of Letters-Patent.

Patented Nov. 2, 1909.

- To all whom it may concern:

Be it known that I, GEORGE MJGRAHAM,

. a citizen of the United States of America,

and a resident of Chicago, in the county of Cook and State of Illinois,have invented certain'new and useful Improvements in Refollowing is aspecification. I

This invention relates to that type of reinforced concrete buildingswhich constitutes the subject matter of my prior patent No. 865,490 ofSept. 10, 1907 and has for its object to provlde a simple and efficientmeans for securing the perforated sheet lathing at the rear of theskeleton reinforcing wire web of a reinforced concrete partition orother like vertical ing, in a'ready and su stantial manner, all as willhereinafter more fully appear.

In the accompanying drawings :Figure l is an elevation of a partitionwith parts broken away to illustrate the present improvement. Fi .2 is ahorizontal section of the same on line w'm, Fig. 1. Fig. 3 is a detailelevation .of a link in an open condition previous to its application.Fig. A, is a similar view of the link in its closed condition. p

Similar numerals of reference indicate like parts in the differentviews.

inforced-Ooncrete Partitions, of which the' Referring to the drawings, 1representsv the reinforcing wires of a partition or other verticalportion of a reinforced concrete building, and which wires under properand uniform tension constitute the metal reinforcing center forapartition or the like, as set forth in detail in my aforesaid patentNO. 865,490, of Sept. 10,1907. I

2 is the perforated lathing sheet of expanded metal or the like, andwhich in the present construction is arranged to the rear of theskeleton wire center 1, and secured in place by the tie or clip piecesthereinafter described, to receive the imposed mass ortion of thebuildof the artition or other vertical portion of the bui ding. N

The feature ofnovelty in the present improvement lies wholly in theconstruction of the aforesaid tie or clip piece l, so that the same canbe easilyv and rapidl applied to afford a strong and substantiaconnection and which by the avoidance of any extended projection of theclip at front permits of the formation of a very thin partition and 56at the same time oifers a minimum interference with'the finishingOperation upon the face of the concrete mass. To the above ends the saidclips are formed of wire and initially have the quadrilateral form shown60 in Fig. 3, with one of the corners thereof cut' away to form the gapor opening 5 and a pair of free prongs 6, which are capable of ready andconvenient introduction around the reinforcing wires 1 and through theper- 'forations of the lathing 2, after which the 1 clips are clenchedor set by a suitable tool into the substantially triangular form shownin Figs. 2 and 4 with the free prongs 6 overlapping each other as shown.

Having thus fully described my said invention what Iclaim as new anddesire to secure by Letters Patent, is:-

The combination in .a reinforced concrete partition,.of a seriesofreinforcing wires in crossed relation, perforated'sheet lathing arraned at one side of said Wires, and clips app ied to said ires at theirintersecting points and embracing adjacent portions of the perforatedlathing to secure the parts togcther, said cli s having an openquadrilateral form initia ly, substantiallyas set forth.
